JOSEPH M. BELL, OF ELLISVILLE, ILLINOIS.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 235,334, dated December 14, 1880. Application filed April 5, 1880. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH M. BELL, of Ellisville, in the county of Fulton and .State of Illinois, have invented certain new and useful Improvements in, Corn-Planters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make andnse the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form. a part of this specification.

My invention relates to improvements in corn-planters of that class in which the seeding devices are actuated automatically from traction-wheels, the object of the invention being to simplify and perfect the mechanism by which motion is transmitted from the wheel to the seed measuring and dropping devices, by combinations and constructions of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a top plan of my improved corn-planter. Fig. 2 is a vertical sectional elevation in the line a: x in Fig. 1. Fig. 3 is a detail sectional plan hereinafter referred to. Fig. 4 is a detail perspective of the oscillating lever.

Referring to the drawings by letters, each letter indicating the same part in'the different figures, letter A represents the forward part of a planter, supported on runners B and provided with tongue 0 and slide D, which connects and operates the dropping devices in the seed-boxes E. F is the rear part, sup ported on wheels Gr Gr, and having axle H and side frame-bars, I I, hinged at their front ends to the forward frame, A. The foregoing constitute the parts of an ordinary corn-planter.

J is a spur-pinion on the hub of one of the wheels, G.

K is an arm, which may be attached to the .axle or to a frame-bar, I, at its lower end, and

its other end extend forward, as shown in the drawings.

L is a short shaft extending through the arm K, and provided with a pinion, M, at its outer end. The shaft L has transverse grooves l l.

A key, N, may be inserted through the groove Z, to, hold the shaft L with the pinion M in gear with the pinion J, and may be inserted in the groove or seat l, to hold it out of gear therewith. (See Fig. 3.)

P is a shaftjournaled in the upper forward end of the arm K, and has a pinion, Q. on its outer end, which gears with the pinion M when said pinion is in gear with the pinion J The inner end of the shaft 1? is extended and has a head, R, secured thereto by a set-screw, S.

Radial arms T T extend in opposite direc' tions from the head It, each having its outer end beveled in an opposite direction from the other.

U is a vibrating lever pivoted at its midlength to the bar I, and its forward end provided with a slot, to.

An arm, V, extends upward from the slide D, and through the slot u in the lever U, so that when the lever U is oscillated in a horizontal plane it will give the necessary reciprocating motion to the slide D for actuating the seed-slides; and it will be seen that,..the arm V will slide in the slot u, and permit either forward or rear frame to be raised or lowered, as desired, and as required in operation, without interfering with the action of the'lever U on the slide D. The rear end of the lever U is beveled at both sides or made sharp at its upper side for some distance back from its fulcrum, and then enlarged at both sides to form cams Y Y, as shown in the drawings.

It will be seen that the arms T are rotated in the evident manner from the wheel Gr, one arm striking on one side of the lever U and the other upon the other, and thus vibrating it and giving motion to the seed-slides as the machine progresses across the field to be planted.

By means of the enlarged ends or cams Y on the lever U the necessary suddenness of movement can be given to the seed-slides.

The parts may be thrown in or out of gear, as hereinbefore described.

What I claim as my invention is- In a corn-planter, the combination, with slide D, having arm V, and centrally-pivoted and slotted lever U, having cams Y Y, of the I In testimony that I claim the foregoing as radial arms T T, beveled in opposite direc- I my own 1 nfiix my signature in presence of 10 tions, shaft 1, and piniuns J M Q, adapted to two witnesses. receive movement from the wheel G, the sevl eral parts constructed and relatively arranged to operate substantially in the manner as and for the purpose herein shown and de- 1 scribed.
